Josh. Sabine, Esq. Dr. Leach had also 
two British specimens of this bird. 
The Glaucous Gull measures (according 
to Temminck) two feet two inches in 
length. 
It inhabits the most northern countries, 
but in greater numbers towards the east 
upon the open sea, and in gulfs ; rare 
upon the shores of the ocean, where the 
young often show themselves in autumn ; 
said to be very common in Russia. It is 
reported to feed upon the dead carcases of 
whales, and on their excrements, as well 
as upon young birds and fish. Voyagers 
assert that it breeds on rocks, aad lays 
greenish eggs r lengthened towards the end, 
and marked with six or eight black spots. 
The young of the first year, and those 
which appear to be one year old, are easily 
distinguished from the young of the Great 
Black-backed Gull by the beak being longer 
and stronger, by the quill shafts being 
always whitish, whereas in the other spe- 
cies they are always black ; lastly, by the 
general shades of grey and brown , which 
are invariably lighter on the young of the
